Anyone know what this noise might be?

The trans am has been doing this for a while, seems to be coming out of the valve cover area on the passenger side. It doesn't bother me much you can only hear it when you accelerate it the way I'm doing it in the video. The valve train and cam are stock by the way. Both belts are new in case anyone wants to know.

Did you inspect the pulleys when you did the belts? Sounds like it could be a bad pulley, or something valvetrain related.

I didn't, I still need to check with out the belts installed.

I think that would be a good place to start.

Videos suck for diagnosing noise. I heard a click every time you got out of the throttle. Was that the noise you're talking about or is it something constant?

Pull the covers, they need some sunlight anyway.
